I have JS5IN1 (jump starter) which hasn't seen the light of day for some
time. The battery is flat, the worklight come son quite brightly but otherwise nothing. I have attempted to charge it using it's own charger plug with little result, the compressor will run for a short time but that's it. I have a "smart" battery charger the instructions of which suggest it might be able to revitalise a flat battery. Can I connect this directly to the JS5IN1 across it's jump cables without doing any damage? Taking the battery out to charge it would probably be a better option but none of my screwdrivers will fit the screws I assume hold the case together. There is a lot of varied expertise in this group so any thoughts? Thanks. |

But like many chargers, it won't even connect to a very flat battery. And any type of lead acid battery isn't going to recover fully after being left flat for a while. It may work well enough for the compressor, but unlikely to ever jump start again. If its own charger does show it to being charged, I doubt you'll do much better with another. -- *A fool and his money can throw one hell of a party.

If you take it apart it will be a standard sized battery but IMHO you would be better off just to buy a lithium one if your main purpose is jump starting (search "jump start" in Amazon or eBay). Never found the torch, pump, or inverter in these "all in 1" units up to all that much. |

Some of them have adaptors to run laptops too, but (as I just found out this morning) they didn't include a plug for the vet's HP. |

Going slightly OT, pulled an apparently dead 105 AH leisure battery out of a caravan yesterday (hadn't been used for months and the charging circuit claimed it was dead when on mains hookup). Gave it best part of a pint of demin water and stuck it on charge on a traditional charger, this morning all the cells are bubbling nicely and it's showing over 14 volts immediately after disconnection. Will stick it on a smart charger for a few days but I'm quite hopeful. |

It's when they look brand new (like the 2 x 12V x 17Ah GEL batteries I recently took out of Dads old mobility scooter) but are completely shot it pains me a little (such a waste etc).

A fine collection of near antique planetary grinders, the baths looked fairly evil. Apparently they fabricate their own "custom" electrodes from lead bars about 10 mm square. They melt down old electrodes and re-cast them, but I didn't see them doing that. |

Lots are 'sealed' these days. Luckily you can get an electronic tester which gives a direct read out of amp.hrs. Not cheap, but a decent battery place should have one. -- *Why do we say something is out of whack? What is a whack? Dave Plowman London SW To e-mail, change noise into sound. |

No real point in keeping a thumping great 100 amp.hr battery if it's well down. Voltage tells you if you have one or more bad cells. Also, it will indicate self-discharge. Depending on what you do with it, as Tim says they may still be useable even if the capacity is down. The owner of this one tells me that in fact he hardly uses the battery (probably why it has been neglected) because he almost goes straight on to mains at sites. I will do a bit of a capacity check once it has had a good charge. |
